Implementation of JSONEncoder
Extensible JSON <https://json.org> encoder for Python data structures.
Supports the following objects and types by default:
+-------------------+---------------+
| Python | JSON |
+===================+===============+
| dict | object |
+-------------------+---------------+
| list, tuple | array |
+-------------------+---------------+
| str | string |
+-------------------+---------------+
| int, float | number |
+-------------------+---------------+
| True | true |
+-------------------+---------------+
| False | false |
+-------------------+---------------+
| None | null |
+-------------------+---------------+
To extend this to recognize other objects, subclass and implement a
``.default()`` method with another method that returns a serializable
object for ``o`` if possible, otherwise it should call the superclass
implementation (to raise ``TypeError``).
default(self, o)
Implement this method in a subclass such that it returns
a serializable object for ``o``, or calls the base implementation
(to raise a ``TypeError``).
For example, to support arbitrary iterators, you could
implement default like this::
def default(self, o):
try:
iterable = iter(o)
except TypeError:
pass
else:
return list(iterable)
# Let the base class default method raise the TypeError
return JSONEncoder.default(self, o)
encode(self, o)
Return a JSON string representation of a Python data structure.
>>> from json.encoder import JSONEncoder
>>> JSONEncoder().encode({"foo": ["bar", "baz"]})
'{"foo": ["bar", "baz"]}'
iterencode(self, o, _one_shot=False)
Encode the given object and yield each string
representation as available.
For example::
for chunk in JSONEncoder().iterencode(bigobject):
mysocket.write(chunk)
item_separator = ', '
key_separator = ': '
_iterencode(obj, _current_indent_level) -> iterable
default = <member 'default' of '_json.Encoder' objects> default
encoder = <member 'encoder' of '_json.Encoder' objects> encoder
indent = <member 'indent' of '_json.Encoder' objects> indent
item_separator = <member 'item_separator' of '_json.Encoder' objects> item_separator
key_separator = <member 'key_separator' of '_json.Encoder' objects> key_separator
markers = <member 'markers' of '_json.Encoder' objects> markers
skipkeys = <member 'skipkeys' of '_json.Encoder' objects> skipkeys
sort_keys = <member 'sort_keys' of '_json.Encoder' objects> sort_keys
